CTS offers an open API, called T4 API, which allows for third party developers to
write their own applications while using the scalability, speed, reliability and
robustness of CTS's back-end. While CTS provides a frontend for users to trade with,
we also offer the T4 API for outside development. For those users who wish to have
some automatic or exotic trading models to pursue the T4 API provides a user friendly
climate in which to develop.
